Idaho Mountain Biking Opportunities

The Croy Creek Trail System is a skills development area jointly managed by BLM and Blaine County located in south-central Idaho, west of Hailey. The trails were designed and constructed primarily for motorcycle riders and mountain bikers, but hikers and equestrians also frequent the system. The trails receive approximately 15,000 - 20,000 visits per season. The Croy Creek Trail System offers mountain bikers a long riding season because of the system's low elevation. The ride experience at Croy Creek includes traditional single track and modernized mountain bike trail features including rollers, berms and table top jumps.

One of the Bureau of Land Management's "Backyard to Backcountry" treasures, information on the  Croy Creek Loop was developed between IMBA and the Shoshone ID, BLM office to provide world-class riding experiences. IMBA's data on the trail includes elevations, ratings, current conditions, photos, and comments.
